Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator temperature-changing drawer and a refrigerator thereof. Background Art

[0002] As people's living standards improve, refrigerators have become an indispensable part of people's lives. A refrigerator usually has two parts: a refrigerator and a freezer. The refrigerator is used to store cold and fresh food, and its temperature is usually higher than that of the freezer, while the freezer has a lower temperature and is used to store food that needs to be stored for a long time or is easy to spoil.

[0003] However, since the volumes of the refrigerator and freezer are fixed, it is impossible for people to fully calculate the amount of food purchased each time and the volumes of the refrigerator and freezer in daily life, so it often happens that one of the refrigerator and freezer has insufficient volume while the other is still empty. Utility Model Content

[0004] Based on this, the utility model provides a refrigerator temperature-variable drawer to solve the above-mentioned technical problems.

[0005] A refrigerator temperature-changing drawer comprises: a first drawer assembly, comprising a first side panel, a second side panel and a first main board, the first side panel and the second side panel are respectively connected to both sides of a first direction of the first main board, and a first matching groove is provided on the upper side surface of the first side panel, and a second matching groove is provided on the upper side surface of the second side panel; a second drawer assembly comprises a third side panel, a fourth side panel and a second main board, the third side panel and the fourth side panel are respectively connected to both sides of the first direction of the second main board, and the third side panel and the fourth side panel are respectively accommodated in the first matching groove and the second matching groove, and can move along the opening direction of the first matching groove and the second matching groove; a cover panel is connected to the upper side surface of the second drawer assembly.

[0006] With such arrangement, the space formed by the first drawer assembly, the second drawer assembly and the cover plate is the volume of the temperature-changing drawer of the refrigerator. The second drawer assembly can be lifted relative to the first drawer assembly. When it is lifted to a certain height, the volume increases, and the items that can be accommodated also increase accordingly. The cover plate can serve as the bottom plate of the upper space of the temperature-changing drawer of the refrigerator to accommodate the items on the upper layer. As the volume of the lower layer (that is, the space formed by the first drawer assembly, the second drawer assembly and the cover plate) increases, the space on the upper layer decreases. Moreover, since the first drawer assembly and the second drawer assembly can move up and down through the first matching groove and the second matching groove and the third side plate and the fourth side plate, the first matching groove and the second matching groove can guide the third side plate and the fourth side plate, so that the movement of the second drawer assembly relative to the first drawer assembly is more stable.

[0007] In one embodiment, when the first drawer assembly and the second drawer assembly are plugged together, the first main board and the second main board are respectively located on both sides of the first side panel, the second side panel, the third side panel and the fourth side panel in the second direction.

[0008] In one embodiment, the upper side surfaces of the third side plate and the fourth side plate are both provided with protrusions, and the cover plate is provided with a groove on the side facing the second drawer assembly, and the protrusion is plug-fitted into the groove.

[0009] In one embodiment, the protrusion includes a connecting section and an enlarged diameter section, and along the first direction, the width of the enlarged diameter section is greater than the width of the connecting section;

[0010] The groove side walls on both sides of the groove are provided with limiting protrusions protruding inwardly, and the two limiting protrusions abut against the two sides of the connecting section in the first direction.

[0011] In one embodiment, a boss is protruded from one side of the cover plate facing the second drawer assembly, and the groove is formed on the boss.

[0012] In one embodiment, the groove extends along the second direction, and a stop plate is provided on a side of the cover plate away from the first main board, and the stop plate covers a notch of the groove on a side away from the first main board.

[0013] In one embodiment, the stop plate and the cover plate are spaced apart from a side surface of the first main board.

[0014] In one embodiment, the first side plate and the second side plate are both connected to the same side surface of the first main plate, and are spaced apart from two edges of the first main plate along the first direction.

[0015] In one embodiment, the third side plate and the fourth side plate are both connected to the same side surface of the second main plate, and are spaced apart from two edges of the second main plate along the first direction.

[0016] The utility model also provides a refrigerator, comprising the refrigerator temperature-changing room drawer and the temperature-changing room as described above, wherein the refrigerator temperature-changing room drawer is installed in the temperature-changing room.

[0017] Compared with the prior art, the utility model provides a first drawer assembly and a second drawer assembly that can move relatively, so that the volume enclosed by the first drawer assembly, the second drawer assembly and the cover plate connected to the second drawer assembly can be flexibly changed in response to the movement of the second drawer assembly, thereby improving the space utilization of the refrigerator.

[0029] The utility model provides a refrigerator temperature-variable drawer 100, whose volume can be freely changed through the cooperation between a first drawer assembly 10 and a second drawer assembly 20, so that the internal space of the refrigerator can be freely adjusted and space waste can be reduced.

[0030] See also Figure 1-Figure 4 The refrigerator temperature-changing drawer 100 includes a first drawer assembly 10, a second drawer assembly 20 and a cover plate 30. The first drawer assembly 10 includes a first side plate 11, a second side plate 12 and a first main board 13. The first side plate 11 and the second side plate 12 are respectively connected to the first main board 13 on both sides of the first direction, and the upper side surface of the first side plate 11 is provided with a first matching groove 14, and the upper side surface of the second side plate 12 is provided with a second matching groove 15; the second drawer assembly 20 includes a third side plate 21, a fourth side plate 22 and a second main board 23. The third side plate 21 and the fourth side plate 22 are respectively connected to the second main board 23 on both sides of the first direction, and the third side plate 21 and the fourth side plate 22 are respectively accommodated in the first matching groove 14 and the second matching groove 15, and can move along the opening direction of the first matching groove 14 and the second matching groove 15; the cover plate 30 is connected to the upper side surface of the second drawer assembly 20.

[0031] In this way, the space formed by the first drawer assembly 10, the second drawer assembly 20 and the cover plate 30 is the volume of the refrigerator temperature-changing drawer 100. The second drawer assembly 20 can be lifted relative to the first drawer assembly 10. When it is lifted to a certain height, the volume increases, and the items that can be accommodated also increase accordingly. The cover plate 30 can serve as the bottom plate of the upper space of the refrigerator temperature-changing drawer 100 to accommodate the items on the upper layer. As the volume of the lower layer (that is, the space formed by the first drawer assembly 10, the second drawer assembly 20 and the cover plate 30) increases, the space on the upper layer decreases. Moreover, since the first drawer assembly 10 and the second drawer assembly 20 are moved up and down by the first matching groove 14 and the second matching groove 15 and the third side plate 21 and the fourth side plate 22, the first matching groove 14 and the second matching groove 15 can guide the third side plate 21 and the fourth side plate 22, so that the movement of the second drawer assembly 20 relative to the first drawer assembly 10 is more stable.

[0032] For explanation, see Figure 1 The first direction refers to the lateral direction of the first drawer assembly 10 and the second drawer assembly 20. Since the refrigerator temperature-changing drawer 100 needs to be placed horizontally in most cases and the lateral width is greater than the longitudinal height, the first direction is parallel to the length direction of the refrigerator temperature-changing drawer 100 in this embodiment, and the second direction is parallel to the front-to-back width direction of the refrigerator temperature-changing drawer 100.

[0033] Preferably, in this embodiment, the first side panel 11, the second side panel 12, the first main board 13 and the third side panel 21, the fourth side panel 22 and the second main board 23 are all vertically arranged, and the first side panel 11 and the second side panel 12 are both perpendicular to the first main board 13, and the third side panel 21 and the fourth side panel 22 are both perpendicular to the second main board 23. The space formed by the above-mentioned side panels is also a rectangular space, so as to improve space utilization and facilitate assembly and processing.

[0034] Furthermore, when the first drawer assembly 10 and the second drawer assembly 20 are plugged together, the first main board 13 and the second main board 23 are respectively located on both sides of the second direction of the first side plate 11, the second side plate 12, the third side plate 21 and the fourth side plate 22. In this way, the second direction (front-back direction) of the volume space is blocked by the first main board 13 and the second main board 23, and the first main board 13 and the second main board 23 are respectively located on both sides, so the first drawer assembly 10 and the second drawer assembly 20 are reversed to form a rectangular space.

[0035] Of course, in other embodiments, the first main board 13 and the second main board 23 may also be located on the same side. Then, two other side panels need to be provided on the other side away from the first main board 13 and the second main board 23 to realize the enclosure of the volume space.

[0036] The upper side surfaces of the third side plate 21 and the fourth side plate 22 are both provided with protrusions 24, and the side of the cover plate 30 facing the second drawer assembly 20 is provided with a groove 31, and the protrusion 24 is plugged into the groove 31. In this way, the cover plate 30 and the second drawer assembly 20 can be fixedly connected by simple plug-in cooperation, and the assembly is convenient, and the assembly can be repeatedly disassembled, which is convenient for subsequent operations such as cleaning or maintenance.

[0037] It is understandable that in other embodiments, the cover plate 30 and the second drawer assembly 20 may also be connected via a snap-fit ​​or mortise and tenon structure.

[0038] Furthermore, the protrusion 24 includes a connecting section 241 and an enlarged diameter section 242. Along the first direction, the width of the enlarged diameter section 242 is greater than the width of the connecting section 241. The groove sidewalls on both sides of the groove 31 are provided with limiting protrusions 311 protruding inwardly, and the two limiting protrusions 311 abut against the two sides of the connecting section 241 in the first direction. In this way, the two limiting protrusions 311 can not only abut against the connecting section 241 and guide its movement along the second direction, but also the enlarged diameter section 242 is located in the groove 31 and is stopped by the limiting protrusions 311, so the cover plate 30 and the second drawer assembly 20 cannot be separated along the vertical direction, and the refrigerator temperature-changing drawer 100 is more stable in daily use.

[0039] Preferably, a boss 32 is convexly provided on one side of the cover plate 30 facing the second drawer assembly 20, and the groove 31 is formed on the boss 32. In this way, the boss 32 allows the groove 31 to have more space, or the groove 31 can be formed deeper without affecting the body of the cover plate 30. This avoids the structural strength of the cover plate 30 being weak at the opening of the groove 31.

[0040] In this embodiment, the groove 31 extends along the second direction. Therefore, when the cover plate 30 is assembled with the second drawer assembly 20, it is necessary to align the protrusions 24 on the third side plate 21 and the fourth side plate 22 with the notches of the groove 31 in the second direction, and then move the cover plate 30 or the second drawer assembly 20 along the second direction, so that the groove 31 and the protrusion 24 move relative to each other in the second direction, so that the protrusion 24 extends into the groove 31.

[0041] A stopper plate 33 is provided on the side of the cover plate 30 away from the first main board 13, and the stopper plate 33 covers the notch of the groove 31 on the side away from the first main board 13. In this way, when the protrusion 24 is already located in the groove 31, the stopper plate 33 can stop the protrusion 24 from moving further along the second direction, thereby preventing the cover plate 30 and the second drawer assembly 20 from moving relative to each other and deviating and disengaging in daily use.

[0042] Furthermore, the stopper plate 33 is spaced apart from the side of the cover plate 30 away from the first main board 13. In this way, the protrusion 24 can have a certain displacement space in the groove 31, thereby offsetting the tolerance of the second drawer assembly 20 and the cover plate 30 during processing, and avoiding that the protrusion 24 is slightly longer than the groove 31 in the second direction after the two are assembled, resulting in the cover plate 30 and the first main board 13 being unable to abut and cooperate.

[0043] In addition, the first side panel 11 and the second side panel 12 are both connected to the same side of the first main board 13, and are spaced apart from the two edges of the first main board 13 along the first direction. In this way, in daily use, there are force points at the edge of the first main board 13, which is convenient for pushing and pulling. It is also convenient for the connection between the first side panel 11, the second side panel 12 and the main board. Similarly, the third side panel 21 and the fourth side panel 22 are both connected to the same side of the second main board 23, and are spaced apart from the two edges of the second main board 23 along the first direction, so as to facilitate the use of the second main board 23 and the assembly between the third side panel 21, the fourth side panel 22 and the second main board 23.

[0044] The utility model also provides a refrigerator, comprising the refrigerator variable temperature drawer 100 and the variable temperature chamber as described above, wherein the refrigerator variable temperature drawer 100 is installed in the variable temperature chamber. The variable temperature chamber is set to an adjustable temperature of -18°C to 5°C, so the refrigerator variable temperature drawer 100 can be used for the storage of articles and food in multiple temperature environments. For example, when the space above the refrigerator variable temperature drawer 100 is a 3°C fresh-keeping area, and the refrigerator variable temperature drawer 100 is a -15°C freezing area, when the demand for frozen food increases, the space of the refrigerator variable temperature drawer 100 can be flexibly increased, and vice versa.

[0045] Compared with the prior art, the utility model provides a first drawer assembly 10 and a second drawer assembly 20 that can move relatively, so that the volume enclosed by the first drawer assembly 10, the second drawer assembly 20 and the cover plate 30 connected to the second drawer assembly 20 can be flexibly changed in response to the movement of the second drawer assembly 20, thereby improving the space utilization of the refrigerator.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
